Clematis plant named ‘Evipo109’

ABSTRACT

A new  Clematis  plant with a compact growth habit, profuse, violet blue flowers, and continuous summer flowering. The variety successfully propagates from softwood cuttings and is suitable for cultivation in commercial nursery culture. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation from vegetative cuttings.

Botanical classification: Genus: Clematis. Species: viticella.

Variety denomination: ‘Evipo109’.

This application claims priority to Plant Breeder's Rights Application Number 2020/2281, which was filed at the Community Plant Variety Rights Office in the European Union on Sep. 21, 2020, the contents of which are hereby incorporated by reference for all purposes.

SUMMARY OF THE CLAIMED PLANT

The present invention constitutes a new and distinct variety of Clematis plant which originated from a controlled crossing between the female seed parent, an un-named seedling, and the male pollen parent, an un-named seedling. Both parent varieties are non-patented.

The two parents were crossed during the summer of 2007 and the resulting seeds were planted the following winter in a controlled environment in Guernsey, Channel Islands, United Kingdom. The new variety named ‘Evipo109’ originated as a single seedling from the stated cross.

The new Clematis plant may be distinguished from its female seed parent and male pollen parent by the following characteristics. The female seed parent grows to a height of 75 cm while the new variety grows to 38 cm in one season. The male seed parent has light violet tepals while the new variety has violet-blue tepals.

The objective of the hybridization of this Clematis plant was to create a new and distinct variety for nursery culture with unique qualities such as:

-   -   1. Uniform and abundant violet-blue flowers;     -   2. Vigorous and compact growth, making the variety suitable for         container culture; and     -   3. Improved disease resistance.

This combination of qualities was lacking in Clematis plants that were in commercial cultivation and the qualities have been substantially achieved in the new variety.

‘Evipo109’ was selected by Mogens N. Olesen and Raymond J. Evison in their Clematis development program in Vale, Guernsey located in the Channel Islands, United Kingdom in 2008. Asexual reproduction of ‘Evipo109’ by means of vegetative cuttings and traditional layering was first performed by Mogens N. Olesen and Raymond J. Evison in the nursery in Guernsey during the summer of 2008. This initial and subsequent asexual propagations have demonstrated that the characteristics of ‘Evipo109’ are true to type and are transmitted from one generation to the next.

FIG. 2 shows leaves. FIG. 3 shows a flowering branch with open flower and flower buds attached. Illustrated plants are 2 years of age.

DETAILED DESCRIPTION OF THE VARIETY

The following is a detailed description of ‘Evipo109’, as observed in its growth outdoor throughout the flowering period in Odense Denmark. Observed plants were cultivated for a period of 24 months in 2 liter containers. Certain phenotypical characteristics of the variety may vary under different environmental, cultural, agronomic, seasonal, and climatic conditions. Color references are made using The Royal Horticultural Society (London, England) Colour Chart, 2001, except where common terms of color are used.

For a comparison, several physical characteristics of the Clematis variety ‘Evipo047’ described and illustrated in U.S. Plant Pat. No. 28,371 are compared to ‘Evipo109’ in Chart 1.
